Method for determining the perfusion
A method is proposed for determining the perfusion by evaluation of the
light emitted by at least one light source and influenced by the arterial
blood, by use of optical measuring means which measure the intensity
variation as a consequence of the variation in arterial blood volume.
According to this method, the perfusion is either displayed as variation
in thickness from the sum of the parallel tissue enlargements d or as
normalized volume. The perfusion is derived by one or more measurements of
light intensity. According to the invention, for the first time a method
for determining perfusion as a quantitative value is provided.
